Abstract
Abstract Arrangement for controlling the internal potential in generator rods by means of a band consisting of semi-conductive web, which is wound helically about the wiring assembly composed of insulated conductor elements. In order to obtain a possibly uniform potential over the entire rod length, the band is reinforced by electrically conductive threads spaced in longitudinal direction, whereby the electrically conductive threads are d-c coupled at a contact point with each other and with a conductor element.
